My base colours are Sally Hansen Gray by Gray, Sally Hansen Thinking of Blue and Sally Hansen Ion. Gray by Gray and Ion are currently available for £1.50 from Fragrance Direct which is quickly becoming my favourite place to shop for polish online!
I attached the studs by painting on a top coat and applying them while it was still wet. The studs on my pointer can be found here and the square studs here, both from Born Pretty Store.
It’s all finished off with a coat of No7 Stay Perfect Top Coat except for on the nails with studs as top coat tends to make the colour run.
